Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

For the vanilla milk:
2 cups whole milk
1 vanilla bean, split and scraped

For the pastry:
1 1/2 cups plus 1 tablespoon all-purpose flour
3/4 cup chilled margarine or unsalted butter
1 pinch salt
4 tablespoons cold water
4 teaspoons white vinegar

For the custard filling:
8 large egg yolks
1/2 cup granulated sugar
1/3 cup plus 1 tablespoon all-purpose flour
2 tablespoons vanilla sugar
21 grams gelatin
1/4 cup unsalted butter
8 large egg whites
1/2 cup granulated sugar
1 teaspoon fresh lemon juice

For the topping:
1/4 cup powdered sugar

Directions

Start by preparing the vanilla milk. Heat the milk in a saucepan over medium heat. Add the scraped vanilla seeds and the vanilla bean pod. Remove from the heat, cover, and let it infuse for 1 hour.

To make the pastry, place the flour in a large bowl and rub in the chilled margarine or butter until the mixture looks like coarse crumbs. Stir in the salt. In a small bowl, mix the cold water and vinegar, then pour this into the flour mixture. Stir just until the dough comes together.

Turn the dough onto a lightly floured surface and roll it into a rectangle. Roll it up, divide it into 4 portions, roll each portion out, stack them, and chill for 20 minutes. Divide the chilled dough into 2 equal halves.

Preheat the oven to 400°F (200°C). Roll out one half of the dough very thin and fit it into a parchment-lined baking pan, about 9 x 13 inches. Prick the surface with a fork and bake until lightly golden and crisp, about 12 to 15 minutes. Repeat with the second half. While the first baked sheet is still warm, cut it into serving-size squares. Leave the second sheet whole for the base.

For the custard, beat the egg yolks with 1/2 cup sugar until pale and thick, about 8 minutes. In another bowl, whisk together the flour, vanilla sugar, and gelatin. Gradually add the dry mixture to the yolks. Remove the vanilla bean pod from the milk, then slowly whisk the warm infused milk into the yolk mixture.

Transfer the mixture to a saucepan and cook over medium heat, stirring constantly, until thickened. Do not let it boil hard. Once thick, remove from the heat and stir in the butter until melted and smooth.

In a clean bowl, beat the egg whites until soft peaks form. Add the lemon juice, then gradually add the remaining 1/2 cup sugar and continue beating until stiff and glossy. Gently fold the warm custard into the beaten egg whites a little at a time until fully combined and airy.

Place the uncut pastry sheet into the pan as the bottom layer. Pour the custard over it and smooth the top. Let it cool slightly, then place the pre-cut pastry squares over the custard, arranging them in the same pattern you will use for slicing later.

Refrigerate for at least 4 hours, or until fully set. Dust generously with powdered sugar before serving. Slice carefully along the pastry cuts for neat pieces.

Variations

A popular variation adds lightly whipped cream on top of the custard before the final pastry layer goes on, creating an even softer and richer slice.

You can also use store-bought puff pastry for a faster version. It will change the texture slightly, but it still gives you the classic flaky contrast.

For a brighter flavor, add a little lemon zest to the custard. For a deeper vanilla taste, use vanilla paste along with the vanilla bean.

Some bakers prefer a firmer custard for cleaner slices, while others like it softer and more delicate. You can slightly adjust the gelatin amount depending on the texture you prefer.

Storage/Reheating

Store Krémes covered in the refrigerator for up to 3 days. It is best enjoyed chilled, as the custard stays firm and the layers hold their shape better.

For the cleanest slices, cut with a sharp knife, wiping the blade between cuts.

This dessert is not ideal for reheating because the custard filling is meant to be served cold. Freezing is also not recommended, since the custard can separate and the pastry may lose its crispness after thawing.

FAQs

What is Krémes?

Krémes is a traditional Hungarian custard slice made with flaky pastry layers and a light vanilla custard filling. It is often finished with powdered sugar on top.

Can I use puff pastry instead of homemade pastry?

Yes, you can use puff pastry for convenience. The result will still be delicious, though the texture may be slightly different from the traditional version.

Why do I cut the top pastry layer before assembling?

Cutting the top layer before placing it on the custard makes the finished dessert much easier to slice neatly without crushing the delicate filling.

How do I know when the custard is thick enough?

The custard should coat the spoon and hold its shape lightly when stirred. It will continue to firm up as it chills.

Can I make Krémes a day ahead?

Yes. In fact, it is even better when made ahead because the custard has enough time to set properly in the refrigerator.

Why is my pastry not staying crisp?

Pastry naturally softens a bit as it sits on the custard. For the best texture, assemble the dessert once the custard has cooled slightly and serve within a day or two.

Can I make this dessert without gelatin?

You can, but the custard will be softer and less stable. Gelatin helps the filling hold its shape for clean slices.

What size pan works best?

A 9 x 13-inch pan works well for this recipe and gives a nice thickness to both the pastry and custard layers.

Can I add whipped cream?

Yes. Some versions include a whipped cream layer for a more bakery-style finish. Add it only after the custard has cooled and started to set.

How should I serve Krémes?

Serve it cold, dusted with powdered sugar, and sliced along the marked pastry squares. It pairs beautifully with coffee or tea.
